Application filed September 2e, 1,924. Serial No. 740,006. i i To allwhom t may concern: l Fig. 5 is a plan of the holder Be it known that I,THOMAS H. MUTH, a Fig. 6 isa vertical sectional view of the l citizen ofthe United States, residing at die; and 4 Paterson, in the county ofPassaic and State Fig. 7 shows the swaged end portion of` a 55 of NewJersey, have invented certain new tube. l

and useful Improvements in Pipe-Flanging In the drawings, is a shellwhich is here Tools, of which the following is a specififormedcylindrical and' open atboth ends.1 cation. One end is somewhat reducedand there is The object of this invention is to provide an inclinedcontinuous shoulder b joining 10 an efficient and simple hand implementthe two interior diametersof the shell. In

whereby ductile pieces may be gaged for a the portion of the shellhaving the lesser swaging operation and then swaged, as interiordiameter are tapped two opposite pieces or lengths of copper tubingwhich screws c. d is a sectional tubular die which require to have theirends swaged so as to has a head ai that snugly fits the larger form themflanged or flaring. In carrying interior .diameter of the shell andbelow the out my invention and in order to produce head an enlargementd2 which fits the animplement of this character of practical smallerdiameter of the shell,fthe diameters value I have had in mind thefollowing: of` the head d `and enlargement d2 being That the implementshould include provi- Joined by a conical shoulder da of the same 20sion for first gaging the portion of the piece taper as the shoulderl b;below the enlargetherein so as to determine the extent to ment (Z2 thedieis preferably of less diamewhich the swaging is carried, or inflanging ter than the lesser interior diameter of the a tube forexample, the'extent of its flange; shell.

The sections abut ing operations the Vimplement in thebest eachother laterally in a zonenear and exform should includeprovision for guiding tending in the present case well down below thegaging or swaging device, as the case the anvil surface d4, as at d,when they are may be; and thatthe implement should be arranged in theshell, which closely encomconstructed in sections so that when thepasses the head portion ofthe die; butfor piece to be operated uponalready lhas one the remaining portion of the die downward end up-set orswaged itcan be removed from the sections are spaced,I as at d?, bybeveling the implement after the other end has been the adjoining facesof the die sections.V swaged. I prefer to form the gaging and swaging Inthe accompanying drawing, 1 means in one piece, as a' cylindrical blocke Fig. l is a vertical sectional ,view of the of metalhaving a gagingprotuberance or 410 implement, with a piece of tubing therein head e atone end and its other end e2 N ready to be shifted to gaged position bythe formed conical.v In its 'function as a swagdevice shown indottedlines, which is a ing device it acts by impact, or vas a hamTcombined gaging andswaging device; mer; hence I term it a hammer swagingFig. 2 is a similar view showingthe parts device. 95

At thistime the holder formed by the die and shell grips the piece f with someslip friction, partly so that the piece will not fall out before it isgaged and so that in the gaging operation it will not under impact ofthe device e be shifted perhaps excessively into Lthe die. The device eis then introduced into the holder, with the head e presented to thepiece f, and byimpact with the latter or otherwise is caused to forcethe piece to the position shown in Fig. 2, or so that the device ewilli-mpi-nge against the end face of head d of the die,

which end forms a gaging surface 6K8. *This will leave the tubing fprotruding somewhat from the die assliown in Fig.- 2. rlihe screws d arethen turned' i-n and act to distort yor bend inward the lower portionsof the' sections of the' die, i.'e., where said sections are spaced bythe beveling at J7, the upper portions of the sections beingk held atthis time by the' shell against radial movement (or practically withoutany spaces being pro-A duced' between the' surfaces at dit) g. thisresults in the lower portion of the die clamping they piece positively,and: as theV upper portions thereof aref held by the shell againstseparating, or so that appreciable spaces are not thusforined betweenthein, the swag'- ing operation can be proceeded' with without formingburrs on the flange produced in coinci'denc'ewith the plane 0K6. Ne'Xtthe device e' is inverted and its conical end being inserted in theholder' (Figi. '3) it is driven into' 'the tube f, expanding its upperend against the die seat d4. lVherr the swagli'ng operation is thuscompleted the screws c' are released so that the'di'el sections andswaged piece may be removed. Inx the present eX- ample the device e whenusedV as a gage abuts for gagingaga-inst the die sections, and'so ifone' section vshould' stand a little higher than' the other they gagingoperation may be made to force them' both down against the shoulder b sothat they will be level when the-y are clamped by the screws c; Havingthus fully described my invention, what I claim as-v new and desire to'secure by Letters Patent is :-Y

l. In a swaging implement, a passaged holder having means to gripsubstantially positively the piecek to be swaged upon the latter beingVplaced in' the passage of said holder'with one end projecting, saidholder having an anvil surface arranged to support said end of the piecein the' swaging and also a gaging abutment adapted to limi-t the gagingthrust of a gaging device to press against said end and force the pieceinto the holder before said means is made to' posi,-

tively grip the piece, in combination with such gaging device' guided insaid holder andA movable against the gaging abutment.
